When the blunderbuss will arrive at my home, i will investigate the name Ketland on it. It might be William or Thomas Ketland instead of Ketland & co (it would make more sense if the butstock is of 1770's design).
I wondered, the pancover has a roller... i always believed they only came into fashion from around 1800's ?

That frizzen roller first appeared in the 1780's, so let's say '1780's' for your blunderbuss. By the early 1800's, the dog has taken on the inverted C-shape.
